Remove the need for resource index path

[0urobor0s]

This removes the need to have an index path if you have a resource that only has a show path requirement

Would you be able to give a more concrete example of where you may need this?

Is it something that can be controlled by customising the dashboard?

[0urobor0s]

Let's say you have a resource A that has many resources B. When I enter the show page for A I want to see all Bs that belong to A and also see the show page for B without having the index page for B.

namespace :admin do
  resources :a
  resources :b, only: [:show]
end

👍 This is much simpler than my approach #1418 and solves the same issue.

Hello @0urobor0s, thank you for your PR and apologies for the delay.

There are two helpers that I think can be used instead of Rails.application.routes.url_helpers.method_defined?.

One is valid_action?, which checks if the route exists (similar to your line), and then there's show_action?, which checks if the user is authorised to see it (if using Pundit as per the docs).

So I think the line could instead be valid_action?(:index, resource) && show_action?(:index, resource).

Also, we'd need a spec for this. Perhaps one around payments only showing as a has_many of orders? (As per the current example app and feature specs).
